U.S. Robotics (often referre to by its abbreviation USR) is a company that makes computer modems and related products. It sold high-speed modems in the 1980s, and had a reputation for high quality and compatibility. With the reduced usage of voiceband modems in North America in the early 21st century, USR is now one of the few modem companies left in that market; its UK page, for example primarily lists updated drivers.
